The SENSe:DATa? query returns the data for the logical frame that contains the
marker on the current waveform in the current window.
The number of data elements returned varies, as follows, with the hardware
settings:
H If the logical frame consists of one physical frame.
The data for the physical frame is sent as it is. The number of data elements
is as follows:
If FFT points = 1,024 : 800 data elements (for baseband and 5 MHz span),
640 data elements (for other settings)
If FFT points = 256 : 160 data points
H If the logical frame consists of two or more physical frames:
The data corresponding to the horizontal range currently being displayed is
sent. The number of data elements is 450, which equals the number of pixels
contained in the area displaying the waveform. The range of the data to send
can be varied by using Horizontal Axis to adjust the horizontal range
displayed.
"DEFINE LENGTH ARBITRARY BLOCK RESPONSE DATA", defined in
IEEE 488.2, is used to return the information. Single precision floating point
data, which consists of 4-byte data elements, returns in Little Endian form.

might return #3644.
Because the GPIB buffer size is restricted, the SENSe:DATa? query must not
repeat as follows:
